We've gone through a couple revisions with different designs. This was the best and there is a heat shield incorporated as well.
That was the most important thing it needed. The ZAC stuff looks to be something custom for larger turbos, I haven't seen anything for a production piece.

Anyways, our intakes will be out soon! The final revision is complete and we're popping them out as I type. ETA mid June :)

We're using our FSB, it can be progressive, PWM etc. You can use 100% or 50/50, whatever you are comfortable with. Nozzle sizes will depend on turbos. If you're stock we rec Dual BM5.
upgraded turbos, Dual 7 and higher depending on how much extra fuel you will need. We'll have more test results up soon, I'll make another thread for it when the time permits.

ZAC has two sizes.. larger inlets for bigger yabeela turbos and standard inlets for stock.

BMS:

Do you have estimated prices for meth kit & intake for M177 motor?
Thanks

Is the BCM available to purchase?
i have a c63s and our company has a mainline Dyno. I’d be happy to provide a before and after run to show the difference.

Zac has a spot on the passenger side intake tube for the AMG plaque.

First impression feedback please.

Those intakes don't look very efficient....

I'm seeing lots of hot air being sucked in where they are positioned.

Would be nice to see dyno gains with a closed hood and a fan positioned in front, most closely simulating road usage. Open hood cheats in a way by allowing plenty of ambient cooler air in and the engine heat to escape.

Will JB4 address pops and crackles limitation on 2019 facelift c63s?

I am very interested in that meth kit. I am running a GLC63 so I’m the same but different lol.

I currently have JB4 installed. Yes it was a hassle as they don’t give you room to move wires. My fat hands had a hell of a time!

Also do the Bluetooth gave me some problems.. I had to actually hard solder it to the box as there was no plug in. It worked! But not sure what went wrong there..

Im currently running weistec w3 turbos, downpipes, DME Tune and weistec air boxes. I’ll tell you the jb4 really took my GLC to the next level.

Here are are photos of after install:

No, to adjust that you need to change injection timing and that isn't something you can safely do with a tuning system. Would need to reflash for that.

is the sound of the exhaust different with additional boost?

Thanks for the honest response!

Anybody throwing any codes?

When Im in map1 or map2 I get:

P0100: Mass Air Flow Circuit Malfunction

P0057: HO2S Heater Control Circuit Low (bank2, sensor 2)

Wondering if anyone else has had them? I talked to another guy with a GLC63 and he is getting samething.

Maps 1&2 should be plug-n-play. Good luck.

Yes I know that....

they are asking me to unplug fuel sensor and plug in stock one to see if it will help with those codes.

We will see if it helps.

Not seen either of those codes. Seems like an o2 sensor is disconnected? In any event work with tech support to help isolate the cause.

Conclusion came to plugging the stock fuel sensors back in and leaving jb4’s disconnected.

Running fine now!

Ah, interesting. Then what’s the point of that connection!?

BMS??

Modifying fuel trims as much as possible to make sure you do not run lean. It does not quite do it like a ECU tune, but good enough to keep everything in check. You can change the FOL (Fuel Open Loop) Value in the app to play with this parameter.

It doesn’t seem like it a plug-n-play. People are still having issues after installation. I’m loving my plug-n-play Dinan.

The JB4 is fully plug and play and unlike Dinan offers fuel control and CANbus. As well as optional boost solenoid control for those really looking to push things. There are maybe 200 C63s tuned with JB4 now and working well.

When people have issues with their car we're always here to provide advice and support as we're doing in this support thread! If you don't want to hear about issues and their resolution don't hang out in support threads. :)

Fuel pressure connections are used to adjust fuel trims in situations where they are maxing out. Reverting those specific connections to stock is a diagnostic step to isolate an issue if codes indicate such. As to the underlining issue in his car I'm not sure what they determined as I wans't involved in the support ticket.
